According to the technical personnel involved in the research and development of Zoomlion, the 101-meter concrete pump is not a “temporary lift” research and development products, but after years of precipitation, and foreign leading technology integration of “meticulous work.” After the merger of Cifa in 2008, after two years of technology integration, in February 2011, the introduction of CIFA composite technology, in the core technology basic research, product development, test and evaluation platform, as well as the improvement of manufacturing processes to make progress, carbon fiber boom technology, active vibration reduction technology, intelligent control technology,
Structural fatigue Research, lightweight research and application, wear-resistant technology, such as a number of major key technologies have made a historic breakthrough in this blow to the challenge of concrete pump car arm length Chongfeng. It can be said that 101 meters is the Zoomlion has launched three Bridges 50 meters, Wuqiao 64 meters, six bridges 80 meters, such as a series of the best bridge length than the concrete pump car, in the Zoomlion Cifa Composite technology platform to build a new generation of composite technology products.
Compared to the general six bridge chassis 80 meters concrete pump, 101 meters in the chassis only increased by 1 bridge, the length of the boom increased by 21 meters to create a concrete pump design in the history of another miracle. At the same time, 101 meters concrete pump car also uses a number of inventions patented technology. Mature Carbon fiber ARM structure 7 arm technology, to reduce the weight of the concrete pump boom by more than 40%, to solve the traditional steel boom fatigue cracking problem, the service life of up to 20 years; the world’s first application of carbon fiber technology cylinder in the field of construction machinery, concrete pump truck total weight loss of more than 15%, high strength,
Long life has greatly reduced the maintenance difficulty of the concrete pump vehicle.
Can “height” determine value? Of course, carrying so high technology content of Zoomlion 101-meter concrete pump truck fu Yi, the advent of many praise at the same time, the industry there are some doubts: the road with 7 bridge chassis meaningless? Once the user buys 101 meters arm frame, whether can appear overweight so that can achieve smoothly on the card? Is such a huge concrete pump turning radius, occupying an area too large? Will there be too heavy weight to make the site impossible to carry? Because the arm frame is too long, the pendulum amplitude is too big, the user can realize the construction smoothly? is the actual use value of the product matched with the high record of the world’s attention when the Zoomlion has greatly refreshed the height record of the concrete pump car boom? A word to the provision of such giants, whether it can be implemented in practical application of the perfect construction?
Not only some peers will be such a question many users also have such a problem.
Before we solve these questions, we may take a look at the actual construction use of the two cases of super high arm concrete pump. September 2011, 31 Heavy industry once the world’s longest 72 meters arm concrete pump car officially delivered to customers Guangdong Zhongshan Crown Machinery Leasing Co., Ltd. That afternoon, the construction site in Nansha, Guangzhou, six bridge Five arms of the monster open front and back legs, vertical height of 72 meters of red arm slowly open, one side of the construction of nearly 30 storeys in front of it become accessible. The world’s longest-arm concrete pump vehicle, means that we have a key engineering, special engineering construction and difficult construction of the strength and ability.
“At that time, Guangdong Zhongshan Guan Li Machinery Leasing Co., Ltd., chairman of the Zhouhuisen reporters said. In less than a year’s time, May 2012, has created the Guinness Book of World Records in 2011, the world’s longest 80-meter carbon fiber arm concrete pump truck, in the Shanxi Lingshi construction, Lingyun’s arm vertical expansion, will C25 concrete pumping continuously to 19 storeys above the high-rise, the picture is spectacular. The vehicle adopts the original arm-frame vibration reduction technology, the arm frame is reduced 60%, the whole vehicle is safe and stable, the operator aerial working is more safe, and the pump delivers the square quantity achieves 200 square per hour, the efficiency is higher.
With exceptional boom stability and exceptional construction adaptability of the 80-meter carbon fiber-reinforced concrete pump car in the first operation of the completion of a continuous operation of 48 hours of construction work.
It can be said that whether 31 of the 72-meter concrete pump truck or zoomlion 80-meter carbon fiber concrete pump car, only from the above two examples of construction cases, we can at least obtain such information: These have been the world record of the long arm of the concrete pump car can withstand the actual construction of the test and in the construction process to obtain a fairly perfect user experience. Then, for Zoomlion launched the 101 meters, in the actual construction can also achieve the same effect, after all, the length of the boom compared with a full upgrade of 21 meters, the question is still heard. In charge of the Zoomlion 101 meters of the relevant research and development personnel to reporters that the advent of 101 meters, and the 80m has the same value concept, is not simply the arm frame, such as the proportion of elongated, not only far view of the super long fishing rods, but not marketing planning gimmick, but the most practical and safe to carry the tripod. In order to ensure the practicality of the 101-meter concrete pump truck, Zoomlion Innovation upgraded a series of technologies, which comprehensively promoted the practical safety and stability of the vehicle. The application of vibration reduction and motion coordination control technology realizes the vibration damping of the boom is more than 50% under the whole working condition. The patented technology of multistage telescopic leg swinging legs, while guaranteeing the span of the leg, reduces the area of the leg by about 35%; the application of load simulation design analysis technology in whole working condition, the load distribution is uniform, and the center of gravity of the jib is 10% lower than that of similar products. Multi-joint, long arm frame composite Motion control patented technology, the realization of the boom fabric efficiency increased more than 15% cloth accuracy increased by more than 20%.
